Double knitted fabric

Abstract

The invention is aimed to provide a three-dimensional marquisette-like knitted fabric that is good in air retainability, air and water conductibility, light transmittance, as well as dimensional stability and shape retainability in the knitting and knitting-width directions, and in linearity; and has unevenness and slippage preventing property on its surface, thus being suitable in various uses. To this end, a three-dimensional marquisette-like structure is made as follows. A double-web knitted fabric is made by warp knitting, and is preferably comprised of the front and back mesh webs (1, 2) and connecting yarns (3) passed between the mesh webs alternately. At least one of the mesh webs (1, 2) has a marquisette-like construction formed by the rows of chain stitches (11, 21) and inlay yarn (5). In addition, connecting yarns (3) for connecting the mesh webs (1, 2) is shifted knitting-width-wise by at least one wale to be passed as slanted at every required course position corresponding to the marquisette-like construction of at least one of the mesh webs.

Description

technical field [0001] The present invention relates to a double-layer knitted fabric formed by warp knitting, which is used for landscaping, interior decoration, bedding, clothing, nursing care, medical treatment, cushioning materials, industrial materials and other various uses . Background technique [0002] In the past, as a double-layer knitted fabric formed by warp knitting on a double-needle bed Raschel warp knitting machine, that is, a double-layer knitted fabric composed of a base material (plain) on the front and back and a connecting yarn connecting the two base materials, there is Both the inner and outer base materials are double-layer knitted fabrics with plain weave, one side of the inner and outer base materials is plain weave and the other is a double-layer knitted fabric composed of reticular tissue, and both the inner and outer base materials are double-layer knitted fabrics with reticular weave. It is used for landscaping, interior decoration, bedding, c...

Problems solved by technology

Moreover, since the protruding part of the connecting yarn cannot be covered with the ground knitting yarn, the touch and quality style of the surface of the base material are damaged, and it is difficult to express the characteristics of the material of the ground knitting yarn.

[0006] In addition, when the above-mentioned double-layer knitted fabric is used as a cushioning material such as bedding or a chair, in order to ensure pressure resistance, the connecting yarn may be a relatively thick monofilament yarn, and the yarns that enter and exit the above-mentioned loop portion may rub against each other. And produce friction sound, bring uncomfortable problem to the user

[0007] As a knitting structure, when weaving the base material of the front and back with a net structure, when connecting adjacent wales or two or more wales with ground knitting yarns such as chain yarns or insertion yarns, in order to perform this connection, Knitting chain yarn or inserting yarn requires more than two pieces of bars. Due to the increase in the number of bars, it not only increases the cost mechanically, but also brings technical difficulties, and reduces the efficiency of looms and knitting.

[0008] In addition, when viewed from the perspective of knitting technology, even if the insertion yarn or other knitting yarn is inserted into the back side of the ground knitting yarn such as chain yarn, the part of the connecting yarn between the front and back base materials does not hold their yarn, The inserted yarn tends to move inwardly between the inner and outer base materials, which cannot produce a sufficient insertion effect and cannot efficiently insert the warp inserted yarn into the inner and outer base materials
